Descartes rule can be used that states that the possible number of positive roots
of a polynomial is equal to the number of sign changes in the coefficients of the
terms or less than the sign changes. The Fundament

f(x)=(2)/(x^2-2x-3)
1. Domain and Range: x=-1,3 y =-1/2, 0
2. x and y Intercept(s): y=-2/3 x=0
3. Horizontal Asymptote(s): y=0
4. Vertical Asymptote(s): x=-1 x=3
f(x)=(x^2 + x - 2)/(x^2-3x-4)
1. Domain and Range: x=-1,4

Module 4 Study Plan
In this module, we begin our study of trigonometry. We use a unit
circle to define the trigonometric functions and to learn their
properties. Trigonometry provides us with the tools to solve a
variety of problems, and can be used to mo

02.05b Writing about Polynomials
The Descartes rule is a type of rule that can be used in order to see all of the possible number
of positive roots of a polynomial, and to see if it is equal to the number of sign changes in the
coefficients of the terms o

Descartes Rule is when the number of sign changes determines all the possible positive rational zeros.
f(-x)= -4(-x)3 + 15(-x)2 8(-x) 3 2 or 0 possible rational zeros
f(-x) = 4x3 + 15x2 + 8x - 3 1 possible negative zero
The sign changes two times in the f

Notice that the shape of the graph line is a diagonal line from the lower left to the upper
right portion of the graph. This shape is a "clue" to the linear relationship between the
variables shown on the graph. When you were an Algebra I student, you lea
